AUTOMATIC AD VERTISIN G-MACHIN E Specification of Letters Patent.

Patented July 16, 1907.

Application filed September 24,1906. Serial No. 336,041.

To all whom it may concern:

Be it known that 1, MAX LEBENB'ERG, merchant, a subject of the King ofPrussia, residing at Berlin, 106 Diisseldorferstrasse, Germany, haveinvented a new and useful Improvement in Automatic Advertising-Machines; and I do hereby declare the following to be a full, clear andexact description of the same.

This invention relates to an automatic advertising machine which on theintroduction of a coin delivers a card which after having been providedwith a certain inscription can be placed in the automatic advertiser insuch manner that it remains permanently in sight of an onlooker, and inthis way exposes to the view of a large number of the public anadvertisement.

The invention is chiefly characterized by the card, or a frame-shapedcard holder, itself constituting a key, so that it can be introducedinto the automatic apparatus Without any special auxiliary means, and insuch manner that it comes into proper position. To this end, the card isprovided with recesses, reliefs and notches or with a specially formededge, but if it be desired to use a card of thin and light material, thesaid card could be placed into a frame which would then be formed insuch manner as to constitute a key for releasing the inlet opening ofthe automatic apparatus.

Several construction of the apparatus according to this invention areillustrated, by way of example, in the accompanying drawings, in whichFigure 1 is a front elevation of the automatic apparatus: Fig. 2 avertical cross-section through a portion of the same on an enlargedscale: Fig. 3 a similar section of another construction of theapparatus. Fig. 4 a part view of the said construction: Fig. 5 a pieceof a card provided With holes near one of its edges, Fig. 6 aconstruction of a slot opening with a card, the latter being providedwith projections of different heights,

Fig. 7 a card formed into a key by notches of varying depths: Figs. 8and 9 show two sections through a special construction of the slotopening: Fig. 10 another construction of the slot opening withcorresponding key card, and Fig. 11 a section through a slot-closingdevice, in connection with a safety device preventing more than adetermined number of cards from being introduced into each row of theapparatus.

At the right hand side of the casing of the apparatus a, is arranged acoin slot b. After introducing into the same a coin of a given value, adrawer 0 can be pulled out and a card d taken out, which can beintroduced into the automatic apparatus in such manner that it will bevisible to the public behind a glass as shown in Fig. 1.

In the'construction shown in Figs. 3 and 4, the upper edge of the card dis made of such shape that it forms a series of teeth which, when thecard is introduced through the lateral slot opening of the apparatus,rotate a small pinion 0, so that the card can be freely introduced fromthe side into the apparatus.

Instead of providing the edge of the card with teeth, holes may beprovided at certain intervals near the edge of the card, as shown inFig. 5, with which holes teeth or pins of a wheel would engage when thecard is being introduced into the slot opening of the apparatus. Theintroduction of the card is in that case possible only if the pitch ofthe toothed wheel corresponds to the distance between the holes.

As an additional precaution, several series of holes may be arranged onthe card. Each row of cards is preferably held closed by flap doors gpivoted' on pins f (Fig. 2) which doors could be opened only by specialemployees when desired, in order to empty the apparatus after it hasbeen working for a certain time.

In the construction shown in Figs. 6, 8 and 9, the slot closing devicecomprises a projecting member h pivoted on pins 71 and held normally inthe closing position shown in Fig. 8, by means of a spring k. Behind thesaid ledge h are provided stop or tumbler pins Z in slots l, on pins727.. These stop pins are controlled by springs n which normally holdthem in the position shown in Fig. 8. It is possible to introduce a cardd into the slot only when the lateral projections d of the said card areof such shape that they can freely pass through recesses h of theprojecting member h. The projections d have, however, in addition topress back the stop pins 1, in the manner shown in Fig. 9, so that thecard d can freely pass over the pins. This is, however, possible onlywhen the length of the different projections d is such that they allstrike the stop-pins Z at the desired moment, in order to enable thecard to pass freely over the stop pins.

The slots 1 in Fig. 6 are at different distances from the ledge h. Aswill be seen in Fig. 10, however, these slots may be arranged at thesame distance from the ledge h and be of the same length. In that caseit is, however, necessary to make the pins Z of different length.

According to the construction shown in Fig. 7, the card of is providedwith recesses of different depth, instead of with projections. Thisconstruction is more practical as the card is in this constructionstronger. The slot closing device may be of various constructions. Theessential point is that it should be possible to open it automaticallyby means of the card, or card holder constituting the key.

The card can be made into a key in a great many other possible ways. Itmay, for instance, be provided with pressed-out projections, or be madecorrugated. In each case it can be formed into a key so long as it isshaped in accordance with certain rules.

After a row of the automatic apparatus has been filled with a propernumber of cards, the slot is closed automatically, a rod or bar p (Fig.11') being shifted by the card which'has been introduced first and whichhas been gradually pushed forward by the other cards. The end r of thesaid bar, bent at a right angle, then engages under a projection t ofthe projecting member h, so that the latter cannot be moved out of itsclosing position. The automatic closing may, however be brought about insome other suitable manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is:-

1. In an automatic advertising apparatus and in combination, acompartment adapted to hold'a plurality of cards and expose them to viewwhen placed in a row, said compartment having a slot forming theentrance thereto, key-controlled means to normally hold the slot closed,and a plurality of cards, each having one edge shaped to form a key tocontrol said means.
